Application filed December 9, 1916. Serial No. 136,077.

T 0 all whom 2'1? may concern:

Be it known that I, Gnonen S. BLanEsLnE, a citizen of the United States, and a resident of Chicago, in-the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dish-lashing Machines, of which the following is a speci fication, reference being had to the accompanying drawings.

My invention relates to dish washing machines and it has for one of its principal objects the provision of a form and arrangement of parts by reason of which the dishes to be washed may be maintained for as; long a period as may be desired in the washing chamber, and by reason of which the dishes are run through the machine by gravity without the necessity for a power actuated conveyer. It is another object of my invention to provide doors or gates which the, machine is divided into compartments such as to prevent any splashing of the water therefrom during the washing and rinsing operations, and to provide means which may be easily and quickly operated for opening and closing such doors or gates as may be desired. It is another object of my invention to provide a form of basket or carrier for the dishes so arranged; as, to cooperate with the doors or gates. for spacing the baskets or carriersin proper posit q l along the machine. It is another object oi my invention to provide a new and improved form of table or apron removably secured in position forming part of the track or pathway of the carriers through the. machine, such tables or aprons being readily removable to afford a cess 'to the operating parts within the tank. It is another object-of my invention to improve. machines of this type in sundry details hereinafter pointed out. The preferred mean. by Whlill I have accomphsned my several objects are illustrated in the drawings and are hereinafter specifically described: That which I believe I to'bc new and desire to cover by this application is set forth in the claims.

Fig. M is a transverse section taken on line l- L.l4 of Fig. 13; and

15 is an end view of the basket of Fig. 1321s seen from the right in said. figure.

Referring to the. several figures of the drawings, in whichcorresponding parts are indicated by the same reference characters,

20 indicates a frame having a ,tank 21 mounted thereon, said tank being divided by to contain wash water, while the compart ment 24 is adapted to contain rinsing water.

The tank 2i is provided at one side thereof with two paddle wheels -26 fixed upon a longitudinallyextending shaft 2'7. The shaft 27 is adapted to be rotated in counterclockwise direction as shown inFigs. l and 3 by means of a sprocket gear 28 fixedly mounted upon said shaft and connected by means of a sprocket chain 29 with a small sprocket wheel 30 rotatable with a third sprocket gear 81. The sprocket gear 31. in turn is driven by means of a sprocket chain 32 extending about a sprocket wheel 3 which is adapted to be rotated at high speed by a. motor 34 of any suitable type.

A special form of sprocket chain 32 is employed in the construction shown by reason of which such chain is rendered coniparatively quiet even when driven at high speed. Such chain 32 comprises links 35 of leather joined by suitable metal links 36.

As is best shown in Fig. 2 an inclined track is provided extending longitudinally through the machine alongside ot the rotary Y paddle wheels 2526. The end portions of of the tank.

this track are provided by means of removable tables or aprons 37-38 at opposite ends of the tank 21. Each of these tables or aprons is supported in position by means of a down-turned flange 39 adapted to hook over a suitable portion of the end wall of the tank 21, the outer end of the apron being supported by means of diagonally-extending brace-bars 4L0 which are slotted at their inner ends for detachably engaging suitable brackets 41 fixed upon the outer i'ace of the end wall (see Fig. 1).

The intermediate portion oi the track or pathway extending through the conmartment 23 of the tank comprises two eiiannrlirons 42 supported by two transversely-eie tending angle-irons 4:3. The angle-irons 43 are removably supported at one side ot the compartment 23 by means oi" slotted braclmts ll and are siu'iporled at their opposite ends by a longitudinally-extcnding angle-iron 45. removably supported at its forward end by a bracket 4-.6 mounted upon the partition 22 and removahly supported at its rear end by a similar bracket 47 mounted upon the wall of the tank 21. In similar manner the section of the track extending through the compartment 24 comprises two channel-irons 2-8 supported at their forward ends by means of transversely-extcnding angle-irons 4-!) which rest upon longitudinally-extending angle-irons 50 supported at their forward ends by brackets 51 mounted upon the wall.

v The rear ends of the channelirons a8 rest upon transverse]y-cxtending angle-irons 52 which are supported by the rear ends of the angle-irons 50 such rear ends of the angle-irons 50 being removably supported by brackets 53 carried by the par- The angle-iron in turn For preventing splashing of the water from the compartments 23-2& of the tank and also to temporarily stop the baskets or carriers hereinafter described, doors 5d, and 56 are provided for closing the ports through which the dishes are adapted to be carried along the longitudinally-extending track. Such doors are slidably mounted in position to close the ports by means of strips 57-58 and brackets 5960 at opposite sides of each door. The doors are supported in their normal closed position by means of brackets 61 mounted in position to receive the lower ends of the doors. These doors are adapted to be operated by means of cables 62 attached to said doors and extending upward therefrom to sheaves or pulleys 63 to which such cables are attached. Tl sheaves 63 are fixedly mounted upon a shalt 64; which is adapted. to be rotated by means of a cable 65 wound about a sheave or pulley 66 also fixedly mounted on said sl aft 6t the lower end of the cable 65 being connected to a foot-lever 67 pivotally mounted on the frame 20. Idler pulleys 68-69 are proi'ided vfor properly guiding the cable As will be readily understood, when the lever 62' is given an operative stroke in counter-clockwise direction in Fig.1, the lower end of the cable 65 will be moved upwart, serving to pull downward upon the upper end portion of said cable for rotating the shaft 64. in clockwise direction in said figure, and sewing to wind the cables 62 about the iiulleys (lfiiior lifting the doors 5st, and 56 in uni son. Counterbalancing means is provided serving to support a portion of: the weight of the doors so as to render them ino nile easily upward, such. means comprisi: a weight 70 carried by the lower end of a cable 7]. wound about a sheave 72 fixedly mounted upon the shaft 64.

The dishes to be washed are carried through the machine along the track tl cthrough by means of baskets or carr i 73 which are provided with supporting wheels '74-. The dimensions of the baskets or carriers 73 are such that four of such carriers are adapted to substantially ill the entire length of track. A flange 75 on the outer end of the table or apron 38 is adapted to stop the foremost one of the baskets or carriers 73. \Vith a second basket or can rier in position upon the track section within 'the compartment 24:, when the gate so is lowered into closing position such gate enllO 1 sea-7,1 6-

out of operative position. The baskets are adapted to be carried about by means of transversely-extending bars or handles 77 mounted in the upper ends of the projections 7 6. Each of the baskets or carriers 73 is provided with longitudinally-extending partitions 78 of any suitable type which are adapted to support in position the dishes placed in the basket.

lVith the motor 34 in operation driving the paddle wheels 2526 in counterclockwise direction in Fig. 8 so as to pick up water from the tank and to throw it toward the leftin said'figure upon and across the track extending through the tank, a carrier'73 provided with a load of dishes to be washed is placed in position upon the apron 37. A downward stroke of the foot-lever 67 serves to raise the doors 54E-55 56, permitting the carrier 73 to enter the washing compartment 23, this result being attained by gravity. The basket 73 is then stopped in position in the compartment 23, and is maintained in position there until the streams of water dashed upon and across the basket have had an opportunity to thoroughly clean the dishes; The -foot lever 67 is then givenanother operative stroke, serving to raise the doors and to permit the basket to enter the l'll'lSlIlg compartment 24, and at the same time permitting a fresh loaded basket to enter the washing compartment 23 from the apron 37, By the time the dishes in the carrier in the compartment 23 are thoroughly cleaned, the dishes in the carrier 1n the compartment 24 will have been thoroughly rinsed. The foot-' lever 67 is then given another operative stroke permitting the leading basket to run by gravity out of the compartment 24 into position upon the apron 38, and permitting acorresponding change in position of the followingbaskets. After three baskets or carriers have been placed in position. the baskets will be automatically brought to proper position by the descending doors 56, as above described, comingin contact with the guides 76; As will be readily understood, by a proper manipulation of the doors 54, 5 5 and 56 a traveling carrier may be stopped in operative position in the several sections of the-tank independently of any other carrier or carriers upon the track, such carrier being stopped by the movement of.

the door into carrier.

hile the machine herein shown and described is designed primarily for use in wae iu dishes, the construction described position across the path of the may also be embodied in machines intended forwashing a variety ofother articles. It

willbe understoodthat I. donotwish to restrict myself totheuse of a stationary track such as is shown in the drawings adapted for usewith. wheeled; carriers, except as herein after specifically clai1ned,but that the invention goes broadly to any suitable supporting means disposed diagonally downward through the tank or receptacle along which supporting means a suitable carrier is adapted, to move by gravity, as above. described. It is alsoto be understood that in referring to sliding doors I do'not, restrict myself to the form of door shown in the drawings, but rather have reference to any suitable type of edgewise-movable door adapted to perform the function described.
